Key Concepts

Mass Number

The mass number is the total count of protons and neutrons in an atom's nucleus. It provides an approximation of the atomic mass and plays a crucial role in distinguishing different atomic species, including the various isotopes of an element.

Isotope

An isotope refers to one of the different forms of a chemical element that have the same number of protons but vary in the number of neutrons. This variation in neutron count leads to differences in the mass number among isotopes, which can affect their physical properties and nuclear behavior.
